The Electro Voice ZLX-15P loudspeakers are equipped with a 1000 Watt (Peak) Class-D power amplifier. They have a transmission range of 42 Hz - 20 kHz. The ZLX-15P active boxes achieve a sound pressure of 127 dB. Both active speakers of the ZLX series are equipped with microphone and line level inputs. The existing combination XLR and jack jacks, an additional Aux-In as a stereo mini-jack connector and an XLR link for looping the signal to another loudspeaker allow versatile connection possibilities. A high-contrast LCD display allows user-friendly operation and allows precise adjustment of the input level. With one-button operation for DSP and existing presets, the performance can be adapted to music style and premises. An LED on the front panel, which can be switched on or off, also provides information on power status.
